XT09-PKC-UA RF Transceiver Modem Equivalent & Substitute Parts

Part Overview

The XT09-PKC-UA is a 900MHz RF transceiver modem manufactured by Digi, designed for wireless communication applications requiring FSK modulation over USB interface. This component operates in the 902MHz to 928MHz frequency band with 1W output power and 115kbps maximum data rate. The product is currently obsolete, making identification of compatible substitute parts essential for system redesign, legacy system maintenance, and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

The XTP9B-PKC-UA qualifies as a direct substitute for the XT09-PKC-UA based on the following critical parameters:

Matching Parameters:

• Frequency range: 902MHz ~ 928MHz (identical)
• Modulation protocol: FSK (identical)
• Interface: USB (identical)
• Sensitivity: -110dBm (identical)
• Supply voltage: 7V ~ 28V (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)
• REACH Status: REACH Unaffected (identical)
• Series: XTend® (identical manufacturer family)

Allowable Variations:

• Data rate increase from 115kbps to 125kbps (backward compatible)
• Power output specification change from 1W to 30dBm (approximately 1W equivalent)
• Product status transition from Obsolete to Active (enables procurement)

These variations remain within acceptable substitution parameters for RF transceiver applications where the core frequency, modulation, interface, and sensitivity specifications are preserved.

Parameter Comparison

Engineering Selection Recommendations

The XTP9B-PKC-UA is the designated substitute for the obsolete XT09-PKC-UA. Selection of this substitute is based on:

• Regulatory Compliance: Both parts maintain REACH Unaffected status, ensuring equivalent environmental and regulatory standing.
• Product Availability: The substitute is Active status, enabling direct procurement and supply chain continuity.
• Functional Equivalence: Core RF parameters (frequency, modulation, sensitivity, interface) are identical, ensuring system-level compatibility.
• Performance Enhancement: The substitute provides increased data rate (125kbps vs. 115kbps) and equivalent power output specification, representing a performance improvement without functional compromise.

Frequently Asked Questions (FAQ)

Q: Can the XTP9B-PKC-UA directly replace the XT09-PKC-UA in existing designs?

A: Yes. Both parts operate in the 902MHz to 928MHz frequency band with FSK modulation, USB interface, and -110dBm sensitivity. The identical supply voltage range (7V to 28V) and moisture sensitivity level ensure mechanical and electrical compatibility.

Q: What is the difference between 1W and 30dBm power output specifications?

A: 30dBm is equivalent to approximately 1W (1000mW). Both specifications represent the same power output level, expressed in different units. The substitute uses the dBm notation standard for RF components.

Q: Does the increased data rate (125kbps vs. 115kbps) affect compatibility?

A: No. The higher data rate of the substitute represents improved performance. Systems designed for 115kbps operation will function with the substitute at the original data rate or benefit from the increased throughput capability.

Q: Why is the XT09-PKC-UA listed as Obsolete?

A: Obsolete status indicates the part is no longer manufactured or supported by Digi. The XTP9B-PKC-UA is the active replacement within the XTend® product family.

Q: Are there packaging differences between these parts?

A: The XT09-PKC-UA packaging is listed as "-" (unspecified in available data). The XTP9B-PKC-UA is supplied in Box packaging. Confirm packaging requirements with your application specifications.

Q: What certifications apply to both parts?

A: Both parts maintain REACH Unaffected status and carry identical ECCN (5A992C) classification, ensuring equivalent export control and environmental compliance.
